Avaliação de impactos na rede elétrica devido a conexão de parque eólico

Abstract

Electrical systems present three operating limits: thermal limit, voltage limit and stability limit. For residential circuit with low voltage levels the analyzes and system conditions are treated by the thermal limit of the components, for high voltage levels systems are usually made stability analyzes, in case of the medium voltage level analyzes are made around the feeder voltage threshold. The focus of this research is the voltage limits of a feeder at several voltage levels. This research presents an analysis in steady state of electrical parameters as voltage, current, power loss, for many cases, when connected to a wind farm in the system characterized by a distribution feeder in Marmeleiro city adjacent to the substation Francisco Beltrão. The proposal is that the installation is carried out at the end line, therefore the study of changes in the circuit is required. Furthermore, it is shown a brief review of the difference in reliability of some of the proposed models, for example, with and without wind farm.
